[QUOTE="jbingham, post: 510339, member: 2640"] Thanks for that, indeed it does, but the regs/guides don't give a wide range of examples so I can't determine whether its OK for one RCD (protecting the board) to do the job or whether each potential problem individual circuit needs its own RCD (an rcbo). That is what iam asking. Would you say the answer to my main question is yes then? PS there is no TNCS involved it is TN-S. The local authority built and owned the houses upontil about 15 years ago I think, and assuming they did elec maintenance, then I would assume they would have installed a rod if necessary. [/QUOTE]
